Description

Portable small hydro power generation system using self-generation function {PORTABLE SMALL-HYBROELECTRIC POWER GNENERATING SYSTEM USING SELF POWER GENERATING}

The present invention relates to a portable small hydro power generation system using a self-generation function.

Hydroelectric power generation is a power generation method that converts the potential energy of water located at a high position into kinetic energy of a generator turbine and produces electricity using electromagnetic induction inside the generator.

Hydroelectric power generation has a limitation in increasing the power generation capacity compared to thermal power generation using fossil fuels, but it is in the spotlight as an eco-friendly energy because the emission of pollutants is remarkably small.

Hydroelectric power generation systems are generally installed by large-scale construction projects, such as dam construction, and large-scale hydroelectric power generation devices have a limited installation location due to this, and a large amount of cost is consumed.

In recent years, in order to solve this problem, a small hydroelectric power generation system using a river or a river as it is has been proposed and installed.

In more detail, the case 110, the accommodating space 118 is formed therein, the accommodating space 118 is sealed to the outside. That is, in a state in which the portable hydroelectric power generation device 100 is installed in water, the receiving space 118 may be formed in a watertight structure so that external water does not penetrate into the receiving space 118 .

The case 110 is exemplarily formed in a cylindrical shape having an elliptical cross-section, and the size of the cross-section decreases from the front side 112 side to the rear side 113 side of the case 110, so that it can be formed in a streamlined shape as a whole. . The case 110 may be formed of, for example, a lightweight plastic or a lightweight metal material with an anti-oxidation treatment.

The front surface 112 of the case 110 is formed in a flat surface, and a partition wall 115 recessed toward the receiving space 118 is formed on the rear surface 113 side of the case 110 . The accommodating space 118 is formed in a shape in which a portion of the rear side of the case 110 is recessed toward the center of the accommodating space 118 by the partition wall 115 .

On the side of the case 110, four case ring portions 111 are formed to protrude, and the case ring portion 111 is a fixed string 500 for maintaining the position of the portable hydroelectric power generation device 100 (see FIG. 5). provides a fixed position for

The aberration unit 120 is provided outside the rear side of the case 110 and is disposed in the aberration unit accommodating space 119 surrounded by the partition wall 150 of the case 110 . The water wheel unit 120 is rotatably connected with respect to the case 110 , is rotated by hydraulic power applied to the portable hydroelectric power generation device 100 , and provides rotational force according to the rotation to the power generation unit 170 .

The aberration unit 120 is rotated about a rotational shaft formed in parallel with respect to a horizontal plane, and the aberration unit body 121 is formed in a cylindrical shape through which the rotational shaft passes through the center, and radially on the outer circumferential surface of the aberration unit body 121 a plurality of blades 122 arranged in 123). At this time, between the partition wall 115 and the rotary shaft 123, the rotation of the rotary shaft 123 is not limited, and a sealing member for suppressing water penetration between the outer peripheral surface of the partition wall 115 and the rotary shaft 123. can be provided. In this case, the sealing member may be a sealing band having an elastic force or a sealing means having a watertight structure therein.

The partition wall 115 of the case 110 is positioned to be recessed toward the receiving space 118 , and the outer surface of the partition wall 115 faces the water turbine unit body 121 and the blade 122 in a spaced apart state.

Like the case 110 , the aberration unit 120 may be formed of a lightweight plastic or a lightweight metal material. At this time, the material of the water wheel unit 120 is resistant to the hydraulic force, so that the water wheel unit 120 is smoothly rotated, and the water wheel unit 120 has a strength that can be suppressed from being damaged.

In the portable hydroelectric power generation device 100 according to the present embodiment, the vertical height of the water turbine unit 120 is formed to be greater than that of the case 110 , and the blade 122 of the water turbine unit 120 is formed in the case 110 . ) is projected based on the upper surface, lower surface and rear side. That is, the blade 122 of the water wheel unit 120 protrudes more than the outer surface of the case 110 . As the blade 122 through which water flows and transmits the force is formed to extend outward more than the size of the case 110, the size of the area on which the force transmitted from the flow of water is applied is formed large, and from this, the power generation efficiency is increased. can be improved

The power generation unit 170 is provided as a pair in the accommodating space 118 in the case 110 . The power generation unit 170 is spaced apart from the center of the accommodating space 118 , and is disposed adjacent to the inner side of both sides of the case 110 . The power generation unit 170 receives the rotational force supplied from the water turbine unit 120, and the magnetic body surrounded by the coil is rotated by the rotational force to generate electric power.

Meanwhile, the power transmission unit 160 transmits the rotational force of the water wheel unit 120 to the power generation unit 170 .

In more detail, the power transmission unit 160 is provided as a pair spaced apart from each other with the water wheel unit 120 interposed therebetween, and is provided in the accommodation space 118 of the case 120 .
